BACKGROUND

All known fragrance compositions include at least one fragrance accord which is a specific combination of fragrance chemicals and, if applicable, other types of raw materials that are used to create a specific olfactive odor that cannot be created from a single fragrance ingredient or essential oil.

Fragrance compositions are used in a variety of consumer products to deliver several benefits ranging from masking unpleasant base or malodors, providing a pleasant olfactory aesthetic benefit, inducing consumer feelings (e.g., happiness, stimulation, relaxation, etc.), and implying a signal of product attributes and function (e.g., freshness, cleanliness, etc.).

Attempts have been made to design fragrance accords and fragrance compositions suitable for specific product applications that have superior or enhanced properties leading to consumer benefits. There are numerous publications teaching the selection of these fragrance ingredients based on their physical, chemical, biological or sensorial properties. For example, WO 1999/065458 defines two categories of fragrance ingredients to be formulated into high impact accords based on a combination of boiling point, partition coefficient (ClogP) and measured odor detection thresholds. These accords can be optionally encapsulated in starch to provide a boost of fragrance from a detergent powder when dispersed in water. U.S. Pat. No. 9,222,055 provides a high intensity fragrance which includes 75% to 100% of at least two key fragrance ingredients having boiling points between 100° C. and 300° C. at a pressure of 760 mmHg, molecular weights within the range of 70 atomic mass units to 175 atomic mass units, and ClogP values between 0 and 4. US 2005/0003975 also discloses perfume compositions composed of high impact accord perfume ingredients classified by boiling point, calculated CLogP, and odor detection thresholds. EP 1 964 54 describes fragrance compositions for use in consumer products to reduce allergic reactions. WO 1997/034987 discloses blooming perfume compositions for use in automatic dishwashing detergent compositions.

In spite of the many attempts described above, there is still a need to design a high performing and high impact bloom fragrance accord.

SUMMARY OF THE INVENTION

One aspect of this invention provides a high intensity bloom fragrance accord for use in a consumer product (e.g., a fabric care product) containing (i) at least 7 wt % (e.g., 7 to 95 wt %) of Class 1 fragrance ingredients, (ii) 5 to 95 wt % (e.g., 5 to 80 wt %, 10 to 80 wt %, and 10 to 70 wt %) of Class 2 fragrance ingredients, and (iii) 0 to 80 wt % of Class 3 fragrance ingredients, in which the Class 1 fragrance ingredients each have an experimental velocity of 8.5 cm/second or greater, the Class 2 fragrance ingredients each have an experimental velocity of less than 8.5 cm/second and greater than 5 cm/second, and the Class 3 fragrance ingredients each have an experimental velocity of 5 cm/second or less.

In some embodiments, the high intensity bloom fragrance accord further contains a malodor counteractive agent in an amount effective to counteracting a malodor. In other embodiments, the high intensity bloom fragrance accord is free of ingredients other than ingredients selected from Classes 1, 2, and 3 ingredients. Namely, the sum of the Class 1 fragrance ingredients, the Class 2 fragrance ingredients, and the Class 3 fragrance ingredients is 100%.

Typically, the fragrance accord comprises at least two (e.g., at least three, at least five and at least seven) Class 1 fragrance ingredients.

In some embodiments, the fragrance accord contains 20 to 100 wt % of the Class 1 and Class 2 fragrance ingredients.

Another aspect of this invention relates to a delivery system comprising one or more fragrance accords described above.

Also within the scope of this invention are bloom fragrance compositions containing by weight of the bloom fragrance composition 5% or more (e.g., 6% or more, 7% or more, 10% or more, and 20% or more) of any fragrance accord described above. These fragrance compositions typically contain at least 3% (e.g., at least 4%, at least 5%, and at least 7%) of two or more of Class 1 ingredients. The bloom fragrance accords of this invention unexpectedly improve the performance (e.g., bloom speed and fragrance intensity) of a fragrance composition.

Still within the scope of this invention relates to a consumer product comprising one or more fragrance accords of this invention, preferably at a level of 0.05 to 20 wt % by weight of the consumer product. Examples of the consumer product include a shampoo, a hair conditioner, a hair rinse, a hair refresher, a hair fixative or styling aid, a hair bleach, a hair dye or colorant, a soap such as a bar soap, a body wash, a cosmetic preparation, an all-purpose cleaner, a bathroom cleaner, a floor cleaner, a window cleaner, a bath tissue, a paper towel, a disposable wipe, a diaper rash cream or balm, a baby powder, a diaper, a bib, a baby wipe, an oral care product, a tooth paste, an oral rinse, an tooth whitener, a denture adhesive, a hand sanitizer, an anti-inflammatory balm, an anti-inflammatory ointment, an anti-inflammatory spray, a bleach, a health care device, a dental floss, a toothbrush, a tampon, a feminine napkin, a personal care product, a sunscreen lotion, a sunscreen spray, a wax-based deodorant, a glycol type deodorant, a soap type deodorant, a facial lotion, a body lotion, a hand lotion, a body powder, a shave cream, a bath soak, an exfoliating scrib, a foot cream, a facial tissue, a cleansing wipe, a fabric care product, a fabric softener, a fabric refresher, an ironing water, a liquid laundry detergent, a powder laundry detergent, a liquid dish detergent, an automatic dish detergent, a unit dose tablet or capsule, a scent booster, a drier sheet, a fine fragrance, a solid perfume, a powder foundation, a liquid foundation, an eye shadow, a lipstick or lip balm, an Eau De Toilette product, a deodorant, a rug deodorizer, a candle, a room deodorizer, a disinfectant, an aerosol antiperspirant, a stick antiperspirant, a roll-on antiperspirant, an emulsion spray antiperspirant, a clear emulsion stick antiperspirant, a soft solid antiperspirant, an emulsion roll-on antiperspirant, a clear emulsion stick antiperspirant, an opaque emulsion stick antiperspirant, a clear gel antiperspirant, a clear stick deodorant, a spray deodorant, a perfume gel, a perfume emulsion, a perfume cream, a perfume oil, a wax, a hair perfume, a cloth perfume, a deodorant perfume, a foaming bath, a bath oil, a bath salt, a bath sachet, a bath crystal, a bath tablet, a perfume jewel, a fragranced polymer, and a fragrance composition for digital devices.

The details of one or more embodiments of the invention are set forth in the description below. Other features, objects, and advantages of the invention will be apparent from the description and the claims.

DETAILED DESCRIPTION OF THE INVENTION

When a cleaning product such as a powder detergent is poured into the water, lathering begins and the consumer starts to experience the fragrance as it evaporates. Conventional bloom analysis does not focus on this stage.

Applicant has found that fragrance ingredients having a high experimental velocity (an indication of the speed of diffusivity) unexpectedly increase the performance of a fragrance accord at the lathering and bloom stage. As such, fragrance ingredients were individually tested for their experimental velocity and were divided into three classes.

Class 1 fragrance ingredients each have an experimental velocity of 8.5 cm/second or greater. Each of these fragrance ingredients typically has (i) at least eight atoms selected from the group consisting of a carbon atom, a hydrogen atom, an oxygen atom, and a nitrogen atom; (ii) a functional group selected from the group consisting of an aldehyde (—CHO), hydroxyl (—OH), olefin (C═C), ether (—O—), ester (—C(O)O—), phenyl, furanyl, and pyrazinyl groups; (iii) a vapor pressure between 0.0003 and 20 mmHg (e.g., 0.003 to 7 mmHg) at room temperature; (iv) a molecular weight within the range of 100 to 280 atomic mass units (e.g., 100 and 200 atomic mass units); and (v) a log P value between 1 and 5.5 (e.g., 1.5 to 4.5). Other suitable functional groups include ketone (R—CO—R), aromatic such as a secondary aromatic amine (Ar—NH—R), carboxylic acid (R—COOH), lactone and epoxide functional groups. In particular embodiments, the functional group is an aldehyde, aromatic or ester functional group. See, Poling, et al. (2000) The Properties of Gases and Liquids, 5th Edition, McGraw-Hill. See also U.S. Pat. Nos. 6,143,707, 6,601,789, US 2004/0138078, and EP 0888440f or additional details concerning the general physical properties of fragrance ingredients.

Class 2 fragrance ingredients each have an experimental velocity of less than 8.5 cm/second and greater than 5 cm/second. Class 3 fragrance ingredients each have an experimental velocity of 5 cm/second or less.

Experimental velocity is calculated as the distance the fragrance travels (60 cm) divided by the speed of diffusivity. The term “speed of diffusivity” refers to the time needed for olfactory detection of a fragrance ingredient measured at a distance of 60 cm from the moment when mixing, with gentle stirring at room temperature (i.e., 25° C.), 2 liters of water and 10 g of a model powder detergent containing an olfactory effective amount of the fragrance ingredient (dosed at 0.005 to 0.1 wt %). The model powder detergent does not contain any other fragrance other than the fragrance ingredient being measured.

The experimental velocity provides indication of how a fragrance ingredient performs at the lather stage and created blooming technical guidelines for consumer products including fabric care products, personal care products, and house care products. The experimental velocity measures how fast a fragrance ingredient evaporates from the water and travels to the nose. Several physical properties of the fragrance ingredient have an impact on the speed of diffusivity such as vapor pressure, molecular weight, Log P, etc.

Unexpectedly, performance at the ingredient level, accord level and total product formulation level had no correlation with previous ingredient performance studies or with known psycho-physicochemical properties and relationships between them. Rather, the speed of diffusivity of fragrance ingredients has a direct impact on the performance of a consumer product in terms of fragrance intensity and room filling capacity.

The term “room filling capacity” refers to the fragrance intensity after 10 minutes from the time when, with gentle stirring at 25° C., mixing 2 liters of water with 10 g of a model powder detergent containing an olfactory effective amount of a fragrance ingredient (dosed at 0.005 to 0.1% by weight of the model powder detergent).

Accordingly, this invention provides high intensity bloom fragrance accords for use in consumer products with enhanced speed of diffusivity, fragrance intensity and bloom/room filling, increased malodor coverage/reduction, fresh and clean fragrance sensory attributes, superior hygiene and increased sustainability.

As is conventional in the art, a “fragrance accord” refers to a mixture or blend of two or more fragrance raw materials or fragrance ingredients. A wide variety of chemicals are known in the art as fragrance ingredients, including compounds such as aldehydes, ketones and esters. More commonly, naturally occurring plant and animal oils and exudates composed of complex mixtures of various chemical components are known for use as fragrance ingredients. In this respect, the fragrance ingredients herein can be relatively simple in their compositions, composed of a single chemical, or can include highly sophisticated complex mixtures of natural and synthetic chemical components, all chosen to provide any desired odor.

In some embodiments, the fragrance accord of this invention is composed of at least 2 (e.g., at least 3, at least 4, at least 5, at least 6, and at least 7) Class 1 fragrance ingredients. In other embodiments, the fragrance accord include at least 10 fragrance ingredients selected from classes 1 and 2 fragrance ingredients, for example, at least 15, at least 20, at least 25, at least 30, at least 35, at least 40, at least 45, and/or at least 50 Classes 1 and 2 fragrance ingredients. The more fragrance raw materials that make up a fragrance accord, the more complex the fragrance accord is considered to be. For example, more simple fragrance accords include a relatively low number of fragrance raw materials, such as less than 10, less than 8, and/or less than 5 fragrance raw materials. In contrast, more complex fragrance accords include a relatively higher number of fragrance raw materials, for example, at least 25, at least 30, and/or at least 40 or more fragrance raw materials.

“Neat” or “neat oil” refers to a fragrance accord that is free from extraneous matter. A neat fragrance accord includes only fragrance ingredients and is unencapsulated and/or unbound from other compounds that would cause a delay in the release of the fragrance ingredients. In certain embodiments, the fragrance accord is a “neat fragrance accord”.

The “bloom” of a fragrance accord refers to the build-up in fragrance intensity and volume that is experienced upon dissolution of a product in use. This can be either an instantaneous “burst” of perfume or a diffusive long term bloom. In accordance with the present invention, “bloom” can be assessed by experimental velocity, odor performance (e.g., fragrance intensity 25 seconds after starting the lathering phase), and/or room filling capability (e.g., fragrance intensity in a closed booth 10 minutes after starting the lathering phase). A fragrance accord with a “high intensity bloom” has an experimental velocity of 8.5 cm/second or greater, odor performance of at least 2.5 and/or room filling capability of at least 2.5 in a sensory scale from 0 to 5, with 0 indicating no smell and 5 indicating a very strong smell.

The fragrance accord of this invention typically has a bloom fragrance intensity index of at least 0.1, (e.g., at least 0.5, at least 1, 0.1 to 5, 0.2 to 4, 0.5 to 3, and 1.5). The bloom fragrance intensity index is the ratio between (i) the sensory intensity score of a fragrance accord or ingredient and (ii) the sensory intensity score of allyl amyl glycolate (AAG), as the standard. The sensory intensity score of AAG is scaled at range of 0 to 100 evaluated by a sensory panel when AAG is dissolved in an appropriate solvent (e.g. diethyl phthalate) at a concentration of 0.015%. The fragrance accord or ingredient is also evaluated by the same panel at a concentration of 0.015%. A score of 5 means that the fragrance or ingredient has a medium smell. A score of 15 indicates that the fragrance or ingredient has a medium smell. A score of 35 indicates a strong smell.

The bloom fragrance intensity score is evaluated as follows: one washed towel is placed in a small booth before the start of the evaluation in order to give enough time to saturate and reach equilibrium concentration in the volume space. The panel evaluates intensity from a window for room filling. AAG is evaluated as a standard. The bloom fragrance intensity index is then calculated as: sensory intensity score of a fragrance accord or ingredient/sensory intensity score of AAG.

Each of Class 1 and Class 2 ingredients has a bloom fragrance intensity of at least 0.1 (e.g., at least 0.2, at least 0.5, 0.1 to 5, 0.2 to 4, and 0.5 to 3).

The fragrance ingredients, standard, accords, fragrance compositions, and consumer products each can be evaluated as described above and can also be evaluated following protocols well-known in the art using different scales, which can be normalized to a scale of 0-100 for calculating the fragrance intensity index.

Each Class 1 ingredient typically has a kinetic energy of more than 5000 joules (e.g., 5001 to 50000 joules and 5500 to 25000 joules). Each Class 2 ingredient has a kinetic energy of 1400 to 5000 joules.

The kinetic energy (KE) of a molecule is calculated using its mass and velocity according to the following equation: KE=½ X mass X velocity². Velocity is the speed of the molecule traveling in an ideal gas, whose molecules occupy negligible space and have no interactions, therefore obeying the gas laws exactly. The kinetic theory assumes that all molecules in a gas state behave ideally, which is plausible for fragrance molecules highly diluted in the air. Not to be bound by any theory, a fragrance molecule having a high kinetic energy can be easily evaporated and travel at a high speed to reach the nose when using in a consumer product.

The vapor pressure of a fragrance ingredient can be readily measured using a manometer or calculated according to the reference program EPI suite v4.00, 2000-2008 U.S. Environmental Protection Agency). Class 1 fragrance ingredients can have a vapor pressure of between 0.0002 mmHg and 20 mmHg at room temperature, wherein the lower limit of the vapor pressure may be 0.0002, 0.0005, 0.001, or 0.005 mmHg, and the upper limit of the amount may be 20, 15, 10, 15, 10, 8, and 7 mmHg at room temperature (i.e., 25° C.). Vapor pressure data for numerous fragrance ingredients are available in the literature. See, e.g., Yaws' Handbook of Thermodynamic and Physical Properties of Chemical Compounds (Norwich, N.Y., 2003).

The molecular weights of the Class 1 or 2 fragrance ingredients can vary, but are preferably within the range of 100 to 280 Dalton, wherein the lower limit of the molecular weight may be 100, 110, 120, 130, 140, 150, 160, 170, 180 or 190 Dalton and the upper limit of the molecular weight may be 280, 270, 260, 250, 240, 230, 220, 210, or 200 Dalton. In some embodiments, the Class 1 or 2 fragrance ingredients each has a molecular weight within the range of 120 to 200 Dalton.

The octanol-water partition coefficient (P) of a material, i.e., the ratio of a material's equilibrium concentration in octanol and water, is well-known in the literature as a measure of hydrophobicity and water solubility (see, Leo, et al. (1971) Chem. Rev. 71:526-616; Hansch, et al. (1968) J. Org. Chem. 33:347-350). High partition coefficient values are more conveniently given in the form of their logarithm to the base 10, log P. While log P values can be measured experimentally, i.e., directly, and measured log P data are available for many perfumes, log P values are most conveniently calculated or approximately estimated using mathematical algorithms. There are several recognized calculation or estimation methods available commercially and/or described in the literature (see, e.g., Leo (1993) Chem. Rev. 93(4):1281-1306). Generally these models correlate highly but may for specific materials produce log P values which differ in absolute terms (by up to 0.5 log units or even more). The log P values of many fragrance ingredients have been reported. For example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Irvine, Calif.) contains many, along with citations to the original literature. In accordance with the fragrance accord of this invention, the log P values of the Class 1 or 2 fragrance ingredients are at least 1.5 units. More specifically, the log P values of the Class 1 or 2 fragrance ingredients are between 1.5 and 5.5 units, wherein the lower limit may be 1.5, 1.6, 1.7, 1.8, 1.9, or 2 and the upper limit may be 5.5, 5, 4.8, 4.6, 4.5, or 4.4. In some embodiments, the Class 1 fragrance ingredients each have a log P value between 1.5 and 5.5, or more preferably between 1.7 and 4.4.

As described herein, fragrance accords were found to have a high impact bloom based upon their experimental velocity, speed of diffusivity, odor performance, and/or room filling capability. In some embodiments, a fragrance accord of this invention has one or more (e.g., at least four, at least 5, and at least 6) Class 1 fragrance ingredients with a speed of diffusivity of 7 seconds or less, as determined by the time of olfactory detection at a distance from the source of 60 cm. In addition, the fragrance accord can have one or more (e.g., at least four, at least 5, and at least 6) Class 2 fragrance ingredients with a speed of diffusivity of greater than 7 seconds and less than 12 seconds. Accordingly, the fragrance accord of this invention has a speed of diffusivity of between 0 and 12 seconds (e.g., between 0 and 8 seconds, between 0 and 6 seconds, and between 0 and 5 seconds), wherein the lower limit may be about 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5 or 4 seconds and the upper limit may be about 12, 11, 10, 9, 8, 7.5, 7, 6.5 or 6 seconds.

The present fragrance accord defines a set of fragrance ingredients which, contrary to conventional physical-chemistry knowledge, perfumery expertise and normal practice, are detected faster by the human nose, have enhanced initial bloom and bloom/room filing sensory performance. The present fragrance accord of this invention also shows benefits such as improved malodor coverage, hygiene, antibacterial, fresh and/or clean attributes. Given the higher level of performance attained with the fragrance accord, lower amounts of fragrance (e.g., 10-30% of conventional fragrances) can be dosed into product formulations thereby reducing the environmental load as well as allergenic issues. In addition, many of the Class 1 fragrance ingredients are available from natural renewable resources (e.g., from fermentation processes or by simple extraction of plant material).

The high intensity bloom fragrance accord of this invention can be used as is (i.e., neat) or dosed from 0.1% to 25% in a fragrance formula to generate a full formula system. Advantageously, both the fragrance accord alone and full formula system are capable of having a speed of diffusivity, an odor performance, and/or a bloom/room filling intensity at parity or higher than the formulas best in class using the same or lower dosage level.

Alternatively, the high intensity bloom fragrance accord of this invention can be encapsulated in a delivery system. A wide variety of encapsulating materials exist which allow for delivery of fragrances at various times in the cleaning or conditioning process. Suitable encapsulating materials a include starches, oligosaccharides, cyclodextrins, polyethylenes, polyamides, polystyrenes, polyisoprenes, polycarbonates, polyesters, polyacrylates, vinyl polymers polyurethanes, amorphous silica, precipitated silica, fumed silica, aluminosilicates, such as zeolites and alumina, and mixtures thereof. In the event that the encapsulating material includes amorphous silica, precipitated silica, fumed silica or aluminosilicates such as zeolite and alumina, the pore volume is at least 0.1 ml/g and includes pores with a diameter between 0.4-10 nm. Suitable delivery systems include those described in WO 2015/023961, WO 2014/011860, U.S. Pat. No. 7,196,049, US 2007/0138674, US 2014/0044760, US 2014/0044761, US 2014/0287008, and US 2013/0330292.

A particular aspect of the present invention is to provide high intensity, consumer acceptable fragrances, suitable for use in consumer products including liquid detergents, powder detergent, bar soap, etc. As secondary benefits, the fragrance accord provides enhanced malodor coverage, superior hygiene, fresh and clean consumer attributes, and/or potentially less environmental and allergenic impacts due to the possibility of using a lower dosage of the invention. Accordingly, the invention also provides a fabric care product containing an effective amount of the high intensity bloom fragrance accord of disclosed herein and an unfragranced fabric care product base. In some embodiments, the high intensity bloom fragrance accord provides enhanced bloom intensity for speed of diffusivity, and bloom/room filling; increased malodor coverage/reduction; fresh and clean fragrance sensory attributes and/or hygiene/antibacterial properties.

The consumer product can contain any fragrance accord described above at a level of 0.01 to 20 wt % (e.g., 0.02 to 10 wt %, 0.05 to 5 wt %, 0.05 to 2 wt %, 0.1 to 0.5 wt %), wherein the lower limit may be 0.01, 0.02, 0.05, 0.1, 0.2, or 0.5 wt %, and the upper limit may be 20, 15, 10, 8, 6, 5, 3, 2, 1, 0.8, or 0.5 wt %.

A standard fragrance probe was used as a comparison and also as a base for diluting Accords A, B, and C. A commercially available fragrance product, i.e., a starch encapsulated fragrance benchmark, was used as comparison.

Each of Fragrance Accords A, B, and C was dosed at 25% in the standard fragrance probe to produce Full Formula System A, B, and C (i.e., 25% fragrance accord A, B, or C+75% standard fragrance probe). Each of the three full formulae systems was dosed at 0.3% and 0.2% in an unfragranced powder detergent base. A panel of six judges evaluated the speed of diffusivity, fragrance intensity of the fragranced powder detergent (i.e., fragrance accord+fragrance probe+unfragranced powder base). Further, the fragrance accords (dosed at 0.1%) were compared to the starch encapsulated fragrance benchmark and the standard fragrance probe (neat oil). The three full formula systems were screened via the trained sensory panel for speed of diffusivity and for fragrance intensity. In the fragrance intensity screening, each fragrance accord was scored in a Labeled Magnitude Scale (LMS) of 0 to 100. A score of 5 indicates that the fragrance accord has a weak smell, a score of 17 indicates a moderate smell, and a score of above 35 indicates a very strong smell. The full formula systems were compared to a total product formulation benchmark, which contains neat oil (0.2%) plus the starch encapsulated fragrance benchmark (0.05% NOE), and also against the standard fragrance probe (neat oil at 0.1%). All statistical results presented were evaluated through ANOVA considering a 95% level of confidence.

Speed of Diffusivity.

The results of this analysis on aged samples (e.g., for 2 weeks) showed that all three fragrance accords had enhanced performance for speed of diffusivity when compared with the reference fragrance probe and the fragrance starch probe. Moreover, unexpectedly, the three fragrance accords showed significantly better speed of diffusivity than the benchmark product. Accords A, B, and C, respectively, had a fragrance intensity of 29.13, 22.91, and 28.39. By contrast, the standard fragrance probe had a fragrance intensity of 16.17 and the starch encapsulated fragrance benchmark had a fragrance intensity of 18.45. As to the speed of diffusivity, Accords A, B, and C, respectively, had a speed of diffusivity of 3.79 seconds, 4.44 seconds, and 4.18 seconds. As a comparison, the standard fragrance probe and the starch encapsulated fragrance benchmark had a speed of diffusivity of 4.74 seconds and 5.74 seconds, respectively.

In terms of the three full fragrance systems, parity levels in terms were observed for speed of diffusivity (one full fragrance system has faster speed of diffusivity also) when compared with the fragrance probe and the benchmark product.

Fragrance Intensity.

Results showed that all three fragrance accords had significantly higher fragrance strength than the reference fragrance probe.

Furthermore, it was observed that all three Full Fragrance Systems A, B, and C had significantly higher fragrance strength than the standard fragrance probe and were parity versus the benchmark product containing a fragrance neat oil and a starch encapsulated fragrance.

Dosed at 0.3% in the powder detergent base, Full Fragrance Systems A, B, and C, respectively, had a fragrance intensity of 18.78, 16.95, and 18.79, and a speed of diffusivity of 4.47, 4.09, and 4.56 seconds. The benchmark product had a fragrance intensity of 18.45 and a speed of diffusivity of 5.74.

Dosed at 0.2% in the powder detergent base, Full Fragrance Systems A, B, and C, respectively, had a fragrance intensity of 16.07, 15.06, and 16.43.

This result was unexpected because the benchmark contained fragrance neat oil plus an encapsulation technology (starch), which is known in the art for providing a significant improvement in fragrance performance at the soaking/bloom stage when in contact with the water phase (for aged samples due to chemical protection of fragrance ingredients against consumer product base). Further, it was observed that any of the full fragrance systems containing the blooming fragrance accord as neat oil had fragrance performance intensities that were parity with a benchmark product which is a full fragrance system (containing a neat oil plus and an encapsulation technology).

Analytical headspace measurement. The headspace of the fragrance probe+accord (accord 25%, probe 75%, total dosage at 0.1%) was measured through standardized analytical dynamic headspace methods and revealed a significantly higher amount of headspace molecules than the probe alone (dosed at 0.1%) both at short and long times after dissolution of the fragranced powder detergent in water. Moreover, odor intensities were calculated from measured peak areas using the odor value concept (OV). Details about the OV model and its applicability to fragrance formulations and sensory perception can be found in the literature. See M. Teixeira et al., Perfume Engineering: Design, Performance & Classification, BH Elsevier, Oxford, U K, 2013. Though this approach it was also observed that the calculated intensity of the odor of the fragrance probe+accord was significantly higher than from the probe alone, thus validating the analytical measurement. This shows the benefit in terms of enhanced fragrance performance of the accords disclosed here.

Malodor Coverage.

The fragrance accords were also designed using the malodor coverage/antimicrobial property database. In this respect, specific fragrance materials with malodor coverage and antimicrobial properties were included in the formulation (e.g., pine super extreme, 3,7-dimethylocta-1,6-dien-3-ol, 3,7-dimethyloctan-3-ol, and 3-ethoxy-4-hydroxybenzaldehyde, among others). For example, it has been found that perfume compositions containing ≥0.05% of at least one of the antibacterial/perfume compositions disclosed in U.S. Pat. No. 6,495,512 can be used to impart interesting herbaceous, citrusy, spicy, floral, sweet and vanillin aromas with earthy, musty and green undertones while having anti-bacterial properties. The results of this analysis showed that the two fragrance accords containing malodor counteractive agents had significant enhancement in malodor coverage levels for mildew and sweat versus the citrus oil benchmark.

Hygiene/antibacterial.

The fragrance accords can contain antibacterial ingredients described above. See U.S. Pat. No. 6,495,512 for a list of suitable antibacterial ingredients. It has been found that fragrance accords of this invention containing ≥0.05% of at least one antibacterial can be used to impart appealing aromas while having anti-bacterial properties. Fragrance ingredients with high antibacterial activity against E. coli, E. hirae, S. aureos and other bacteria include 1-methoxy-4-methylbenzene, 3,7-dimethylocta-1,6-dien-3-ol, and pine super extreme, among others.

Examples 4 and 5

Accord D of this invention was prepared by using (i) 8.1% of four Class 1 ingredients: rose oxide, galbascone, tropicalia, and ethyl-2-methyl butyrate.

Fragrance 1 of this invention was prepared by adding 5 parts of Accord D to 75 parts of fragrance Serena (Commercially available from International Flavors & Fragrances, Union Beach, N.J.). Fragrance Serena contained only 0.375% of Class 1 ingredients and was used as a control.

Shampoo Composition 1 of this invention was prepared by dosing Fragrance 1 in an unfragranced model shampoo base at a level of 1%. The shampoo composition was macerated for at least 24 hours at room temperature before evaluation.

A comparative shampoo composition was prepared by mixing fragrance Serena with the unscented shampoo base at the same dosage as Shampoo Composition 1.

Shampoo Performance

Shampoo Composition 1 and the comparative shampoo composition each were applied to wet hair swatches with excess water squeezed out. The hair swatches were then lathered and rinsed with water.

A trained panel of judges evaluated the fragrance intensity on a scale ranging from 0 to 100. A numerical value of 5 indicated the hair swatches produced a weak intensity, while a value of 30 indicated the hair swatches generated a very strong smell.

Unexpectedly, the hair swatches treated with Shampoo Composition 1 had a fragrance intensity of 13.6 at the bloom stage while the hair swatches treated with the comparative shampoo composition had a fragrance intensity of 12.6.
